Threshold measurements with a Prcitronic KH 70 bone vibrator were carried out on 25 young, otologically normal subjects (50 ears) in the frequency range between 125 Hz and 8 000 Hz. The vibrator was applied to the human mastoid as well as to the forehead. The non-test ear was masked. ...
For a frequency of 1 kHz, the threshold of hearing is ___. The Threshold for Hearing: The unit used for detecting and measuring pure tones is called PHON. The sound is the form of energy that produces the sensation of hearing in our ears and the audible range in terms of frequency...

Threshold shifts in the average human ear are dependent upon the physical parameters of the noise to which the ear is exposed. The influence of noise level can be described approximately by an exponential function. High‐frequency noise components cause much greater threshold shifts than low‐frequen...

Children with minimal hearing impair- ment perform less well on tests of educational performance, particularly in areas related to language (8). Furthermore, those with poor linguistic abilities perform less well on tests of acoustic frequency and temporal resolution (9,10). These find- ings are...
